About the Airtac SC50 Standard Cylinder SC50X150SLB
The SC50X150SLB is a double-acting pneumatic cylinder delivering 982 N of push force and 825 N of pull force at 0.5 MPa. With a 150 mm stroke and a 20 mm diameter piston rod, it fits medium-force clamping, pressing, and lifting tasks where a compact tie-rod design is preferred.
This model includes a built-in magnet (suffix -S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling rod-position feedback without external brackets. The LB foot mount (F-SC50LB) provides stable axial surface mounting, and the TPU seals offer reliable operation from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X150SLB Is Used
Part Stops & Gates
The 150 mm stroke and 982 N push force at 0.5 MPa reliably stops pallets or boxes on gravity conveyors. The built-in magnet allows end-of-stroke sensing to sequence material flow.
Clamping Fixtures
Apply consistent 825 N pull force for pneumatic workholding in CNC or welding jigs. The LB foot mount secures the cylinder rigidly to the machine bed for repeatable clamping cycles.
Press & Assembly Tools
Generates up to 1767 N at 0.9 MPa for light press-fit assembly or riveting. The adjustable air cushion decelerates the 20 mm rod smoothly at stroke end, reducing impact on tooling.
Is the Airtac SC50 Standard Cylinder SC50X150SLB the Right Cylinder?
For higher force, step up to the SC63 bore (1559 N push at 0.5 MPa); for a lighter, more compact actuator, the SC40 delivers 628 N. This 150 mm stroke is well within the 1200 mm maximum standard stroke for 50 mm bore cylinders.
When replacing, match five points: 50 mm bore, 150 mm stroke, PT port thread, LB foot mounting, and the -S magnet for sensor compatibility. The SC is a tie-rod cylinder and does not interchange dimensionally with ISO 15552 profile cylinders.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC50 Standard Cylinder SC50X150SLB FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. It directly replaces another AirTAC SC50 cylinder with the same stroke, PT ports, LB mount, and magnet option.
